Problem Note 58780: Hadoop Distributed File System (HDFS) file and directory names should not begin with an underscore
 |  |  |  |
Hadoop Distributed File System (HDFS) file and directory names that begin with an underscore (_) are reserved names in Hadoop that correspond to a hidden system file. Although SAS® software might at times allow you to create a file that begins with an underscore, Hadoop automatically filters these files from processing since they are hidden system files.
In a future release of SAS software, an error message will be generated if you attempt to create HDFS file or directory names that begin with an underscore.
